Surface Properties of Surfactant Solutions
The goal of my project was to characterize water-surface quality and physics in the presence of surfactants, which are substances that reduce
a liquid’s surface tension. Aerosol production is important for atmospheric processes. Sea-spray aerosols are produced by bubbles bursting at the ocean’s surface, and surface properties can be impacted by surfactants. I worked in the lab taking pictures over different periods of time of drops made from different surfactant solutions and of varying concentrations. I determined the surface tension of these drops and organized them for future reference. I then filmed the drops as they oscillated so that I could determine their surface tension and surface area. My contributions consisted of data on the surface properties of water and the experimental setup for future projects. From this experience, I became more familiar with reading academic scientific writing, working in a lab, and setting up experiments. This internship affirmed my desire to continue studying mechanical engineering, particularly for future work in industry.
